[0035] To make the objectives, technical solutions, and advantages of the embodiments of this utility model clearer, the technical solutions of the embodiments of this utility model will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of this utility model, not all embodiments. The components of the embodiments of this utility model described and shown in the accompanying drawings can typically be arranged and designed in various different configurations.

[0036] First embodiment:

[0037] A cover plate swing lifting device, such as Figure 1 and Figure 2 As shown, the toilet includes a seat assembly installed on the toilet 13. The seat assembly includes a seat body 1 and a support frame 2. The support frame 2 is fixed to the rear end of the toilet 13. The seat body 1 is movably mounted on the support frame 2. A lifting device is provided between the seat body 1 and the support frame 2. A locking device 7 and an unlocking device 8 are also provided between the seat body 1 and the support frame 2. When the toilet 13 is in normal use, the unlocking device 8 locks the seat body 1 on the support frame 2. When the unlocking device 8 unlocks the locking device 7, the lifting device drives the seat body 1 to rise, making it convenient for the user to clean the bottom of the seat.

[0038] The lifting device includes a linkage assembly and a drive assembly 5. The cover plate body 1 is movably connected to the support frame 2 via the linkage assembly. The drive assembly 5 is used to drive the cover plate body 1 to lift. One end of the drive assembly 5 is hinged to the cover plate body 1, and the other end is hinged to the support frame 2. The linkage assembly is used to guide the cover plate to swing horizontally to make room. The linkage assembly includes at least one set of linkages. In other embodiments, only one set of linkages may be provided. In this embodiment, it includes a first linkage 3 and a second linkage 4. One end of the first linkage 3 and the second linkage 4 are respectively hinged to the bottom of the cover plate body 1, and the other end is respectively hinged to the support frame 2. The hinge points of the first link 3 and the second link 4 with the support frame 2 are closer to the front end of the toilet 13 than the hinge points with the lid body 1. This causes the lid body 1 to swing forward when it is raised, thus making it suitable for lids of various shapes and ensuring that the lid does not hit the wall after being raised. In other embodiments, the hinge positions of the link assembly and the drive assembly 5 on the lid body 1 and the support frame 2 can be adjusted according to the different clearance positions required, so as to finally achieve horizontal swing clearance.

[0039] like Figures 3 to 5As shown, the driving assembly 5 includes a first push rod portion 501 disposed on the cover plate body 1, a second push rod portion 502 disposed on the support frame 2, and a thrust module. The first push rod portion 501 and the second push rod portion 502 are slidably connected relative to each other. One end of the first push rod portion 501 is hinged to the cover plate body 1 relative to the cover plate body 1, and one end of the second push rod portion 502 is hinged to the support frame 2 relative to the support frame 2. The thrust module drives the first push rod portion 501 and the second push rod portion 502 to slide relative to each other, thereby lifting the cover plate body 1. In this embodiment, the top of the first push rod portion 501 is hinged to the cover plate body 1, and the bottom of the second push rod portion 502 is hinged to the support frame 2. When unlocking, the thrust module pushes the first push rod portion 501 upward, thereby lifting the cover plate body 1.

[0040] The first push rod portion 501 is sleeved on the second push rod portion 502. The thrust module is a second elastic element, which can be a compression spring 503. The two ends of the compression spring 503 are in contact with the first push rod portion 501 and the second push rod portion 502, respectively. When the locking device 7 locks, the compression spring 503 is compressed. When unlocking, the compression spring 503 rebounds and pushes the first push rod portion 501 upward. A telescopic rod is also connected between the first push rod portion 501 and the second push rod portion 502, and the compression spring 503 is sleeved on the outside of the telescopic rod. A cylinder head 12 is provided at the opening of the first push rod portion 501. A protruding flange protrudes from the top peripheral wall of the second push rod portion 502. When the first push rod portion 501 is extended to its full position, the cylinder head 12 abuts against the protruding flange, limiting the maximum stroke of the first push rod portion 501. A sealing ring 11 is provided between the opening of the first push rod part 501 and the peripheral side wall of the second push rod part 502 to form an installation cavity. The first push rod part 501, the second push rod part 502 and the sealing ring 11 form an installation cavity. The thrust module is located in the installation cavity. A pressure relief hole is provided on the first push rod part 501. The pressure relief hole connects the installation cavity to the outside. After the first push rod part 501 is started, gas is slowly injected into the installation cavity, thereby achieving slow lifting.

[0041] Furthermore, a first elastic element is provided on the connecting rod. In this embodiment, a first elastic element, which is a torsion spring, is provided at the hinge of the first connecting rod 3 and / or the second connecting rod 4. When the locking device 7 is locked, the torsion spring is compressed. When the locking device 7 is unlocked, the lifting device raises the lid body 1, and the torsion spring assists the connecting rod in swinging. The first connecting rod 3, the second connecting rod 4, and the drive assembly 5 are arranged sequentially from the rear end to the front end of the toilet 13. The height at which the second connecting rod 4 pushes open the lid body 1 is greater than that of the first connecting rod 3, and the height at which the first push rod 501 pushes open the lid body 1 is greater than that of the second connecting rod 4, so that the front end of the lid tilts upward at a certain angle when it is raised, making it easier to clean.

[0042] The locking device 7 includes a limiting boss 701 on the outer wall of the first push rod portion 501, and a limiting slider 702 slidably connected to the support frame 2. The limiting slider 702 is used to limit the limiting boss 701. The limiting slider 702 has a groove. When the limiting slider 702 is in the first position, the limiting boss 701 enters the groove to engage with the limiting slider 702, thereby locking the first push rod portion 501 and the second push rod portion 502 in a compressed state. When the limiting slider 702 is in the second position, the limiting boss 701 disengages from the groove and can separate from the limiting slider 702. The thrust module drives the first push rod portion 501 and the second push rod portion 502 to slide and extend relative to each other, thereby allowing the first push rod portion 501 to be pushed upward. In other embodiments, the limiting boss 701 may also be provided on the second push rod portion 502. When the limiting boss 701 is provided on the second push rod portion 502, the limiting slider 702 is slidably connected to the cover plate body 1. The cooperation principle between the limiting slider 702 and the limiting boss 701 is the same as above.

[0043] In this embodiment, the locking device 7 is located at the front end of the cover plate body 1 and also includes a locking assembly located at the rear end of the cover plate body 1. The locking assembly locks the cover plate body 1 and the support frame 2. The locking assembly includes a buckle 601 located at the rear end of the cover plate body 1, and a lock buckle 602 on the support frame 2 that engages with the buckle 601. The lock buckle 602 is slidably connected to the support frame 2 to achieve engagement and disengagement with the buckle 601. The buckle 601 has an elastic arm. When the cover plate body 1 is installed, the buckle 601 automatically engages with the lock buckle 602, improving the situation where the front end of the cover plate is locked but the rear end is open after locking. When unlocking, the lock buckle 602 moves away from the buckle 601, causing the lock buckle 602 to separate from the buckle 601. In other embodiments, the buckle 601 can be located at the rear end of the support frame 2, and the latch 602 is set in conjunction with the buckle 601 and slidably connected to the cover plate body 1. The latch 602 is set in relation to the swing block 804. When the swing block 804 is set on the support frame 2, the latch 602 is set on the support frame 2. When the swing block 804 is set on the cover plate body 1, the latch 602 is set on the cover plate body 1. The latch 602 can also be swayed and set on the rear support frame 2 of the cover plate body 1. Similar to the sliding, the latch 602 has positional movement before and after the swing, and the latch 601 is engaged and disengaged through the positional movement.

[0044] like Figures 6 to 9 As shown, in this embodiment, the unlocking device 8 includes a button assembly 801 and a wire rope assembly. The button assembly 801 drives the locking device 7 to unlock via the wire rope assembly. The wire rope assembly includes a traction rope 802 and a linkage rope 803. The button assembly 801 drives the limit slider 702 to slide via the first driving member, i.e., the traction rope 802. The button assembly 801 also drives the latch 602 to slide via the pulling member, i.e., the linkage rope 803, so that the unlocking device 8 simultaneously releases the locked state of the cover plate body 1 and the first push rod part 501.

[0045] The button assembly 801 includes a button box 8011, within which a latch 8012 for user pressing is movably disposed. A swing rod 8013 is hinged within the button box 8011. The latch 8012 contacts one end of the swing rod 8013, and a traction rope 802 is connected to the other end of the swing rod 8013. When the latch 8012 presses down one end of the swing rod 8013, the other end of the swing rod 8013 rotates to the other side, thereby pulling the traction rope 802. A spring for resetting is fitted on the latch 8012, automatically resetting the latch 8012 after pressing. A patch 14 for user convenience is also fixed on the latch 8012.

[0046] In this embodiment, the unlocking device 8 further includes a swing block 804 hinged to the support frame 2. The swing block 804 is used to coordinate the sliding of the limiting slider 702. The swing block 804 can coordinate the sliding of the limiting slider 702 with the first driving member and at least one limiting slider 702, or it can coordinate multiple limiting sliders 702. In this embodiment, the limiting slider 702 is slidably connected to the support frame 2, and the swing block 804 is also hinged to the support frame 2. In other embodiments, the swing block 804 can also be hinged to the cover plate body 1. When the limiting slider 702 is slidably connected to the cover plate body 1, the swing block 804 is hinged to the cover plate body 1.

[0047] The swing block 804 includes a driving end and a driven end. When the direction in which the limiting slider 702 moves from the first position to the second position is the same as the driving direction of the first driving member, the first driving member is connected to the driving end of the limiting slider 702 or the swing block 804, and there is a transmission connection between the limiting slider 702 and the driving end of the swing block 804. When the direction in which the limiting slider 702 moves from the first position to the second position is opposite to the driving direction of the first driving member, the limiting slider 702 is connected to the driven end of the swing block 804, and there is a transmission engagement between the first driving member and the driving end of the swing block 804. In this embodiment, specifically, two limiting sliders 702 are provided, respectively located on opposite sides of the second push rod portion 502. The outer wall has a centrally rotatably connected to the support frame 2. The driving end and driven end of the swing block 804 are respectively connected to the limiting sliders 702 on both sides. One limiting slider 702 moves from the first position to the second position in the same direction as the unlocking direction as the first driving member. This limiting slider 702 is connected to the first driving member and is hinged to the driving end of the swing block 804. The other limiting slider 702 unlocks in the opposite direction and is connected to the driven end of the swing block 804. A first reset member, which provides elastic force to the swing block 804, is provided between the swing block 804 and the support frame 2. The first reset member is a reset spring 805. In other embodiments, the limiting slider 702 moves from the first position to the second position in the same direction as the first driving member. This limiting slider 702 can be connected to the swing block 804, and this limiting slider 702 is hinged to the driving end of the swing block 804.

[0048] One end of the linkage rope 803 is connected to the driven end of the swing block 804, and the other end is connected to the latch 602. In this embodiment, the unlocking direction of the latch 602 is opposite to the driving direction of the first driving member, and the pulling member is connected to the driven end of the swing block 804. In other embodiments, when the unlocking direction of the latch 602 is the same as the driving direction of the first driving member, the pulling member can be connected to the driving end of the swing block 804. In this embodiment, when the traction rope 802 pulls the limiting slider 702 to slide, it drives the swing block 804 to rotate, causing the two limiting sliders 702 to move in opposite directions and unlock simultaneously. When the swing block 804 rotates, it compresses the return spring 805 and pulls the latch 602 to slide, thereby unlocking the latch 602. A return spring 805 is also provided on the side of the latch 602 away from the buckle 601. When the traction rope 802 stops pulling, the two return springs 805 respectively drive the swing block 804 and the latch 602 to reset.

[0049] In this embodiment, as Figure 1As shown, it also includes a locking assembly 15, which is located between the support frame 2 and the toilet 13. The locking assembly 15 is used to lock the support frame 2 and the toilet 13. Unlocking the locking assembly 15 allows the seat assembly to be completely removed from the toilet 13. Locking the locking assembly 15 fixes the seat assembly to the toilet 13.

[0050] The working process of this utility model is as follows:

[0051] When the cover body 1 needs to be raised, press the buckle 8012 on the button box 8011. The traction rope 802 pulls the limit slider 702, which is connected to the drive end of the swing block 804, to move. The swing block 804 drives the limit slider 702 on the other side, which is connected to the driven end of the swing block 804, to move. Finally, the first push rod part 501 is released from the lock. At the same time, the swing block 804 rotates, pulling the linkage rope 803 connected to the driven end of the swing block 804 to move and release the lock 602. The compression spring 503 automatically pushes out the first push rod part 501. At the same time, the torsion spring also drives the connecting rod to swing, so that the cover body 1 is raised forward and upward.

[0052] Second embodiment:

[0053] A cover plate swing lifting device, such as Figures 10 to 12 As shown, the difference from the first embodiment is that the locking device 7 in this embodiment is located between the first push rod portion 501 and the second push rod portion 502. The locking device 7 includes a limiting block 703 slidably connected to the second push rod portion 502. The first push rod portion 501 has a locking groove 704. When the limiting block 703 is in the third position, the limiting block 703 passes into the locking groove 704, thereby locking the first push rod portion 501 and the second push rod portion 502 in a compressed state. When the limiting block 703 is in the fourth position, the limiting block 703 disengages from the locking groove 704, and the first push rod portion 501 and the second push rod portion 502 slide relative to each other to lift the cover plate body 1. In other embodiments, the limiting block 703 is slidably connected to the first push rod portion 501, and the second push rod portion 502 has a locking groove 704.

[0054] The first push rod portion 501 and the second push rod portion 502 are sleeved together. A first guide sleeve is disposed within the first push rod portion 501, and a second guide sleeve is disposed within the second push rod portion 502. When the first push rod portion 501 and the second push rod portion 502 are sleeved together, the first guide sleeve and the second guide sleeve are simultaneously sleeved together, and the first guide sleeve and the second guide sleeve slide relative to each other. The first push rod portion 501 is sleeved outside the second push rod portion 502, and the second guide sleeve is sleeved outside the first guide sleeve.

[0055] The first guide sleeve is provided with a snap-fit ​​groove 704. The unlocking device 8 includes a push block 806 slidably connected within the snap-fit ​​groove 704. A limiting block 703 is provided on the second guide sleeve corresponding to the position of the push block 806. The limiting block 703 passes through the snap-fit ​​groove 704 on the first guide sleeve, snaps into the snap-fit ​​groove 704, and abuts against the push block 806. A starting block 807 is slidably connected inside the first guide sleeve. The starting block 807 is connected to a second driving member.
